Description	Insulin is a double-chain (α, β) polypeptide hormone secreted by islet β cells in the pancreas. It consists of 51 amino acids, of which the α chain contains 21 amino acids and the β chain contains 30 amino acids. The two chains are connected by two pairs of disulfide bonds, and the α chain itself also contains a pair of disulfide bonds. The secretion process of insulin is: the amino terminus of preproinsulin carries a 23-30 amino acid signal peptide. This signal peptide can transfer preproinsulin to the endoplasmic reticulum, and then is immediately cut off to release proinsulin. Proinsulin is composed of insulin β chain, C-peptide and α chain. The released proinsulin is immediately transferred to the Golgi apparatus, where it is packaged and converted into insulin, and is released into the blood together with C-peptide. Insulin is the only protein hormone known in the body that can lower blood sugar. It is not only responsible for regulating the uptake, utilization and storage of glucose, amino acids and fatty acids by cells, but also inhibits the degradation of glycogen, protein and fat. This product is a full-length sequence of human insulin expressed in E. coli. The molecular weight is approximately 5800 Da. The structure is the same as that of naturally derived human insulin. It is commonly used as an auxiliary component in cell culture. The common concentration is 1~10 μg/mL. Host Cell Protein < 10 ng/mg Microbial Limit < 300 cfu/g
Appearance	White powder
Molecular Formula	C₂₅₇H₃₈₃N₆₅O₇₇S₆
Intended Use	Recombinant human insulin is supplied in powder form. This product is usually dissolved in a dilute hydrochloric acid solution (10mM) to prepare a stock solution containing 1-2mg per 1ml, which is then sterilized and filtered. The filtrate can be stored at -20 ℃ for 6 months after packaging. Repeated freezing and thawing should be avoided.
Molecular Weight	5808
Source	E.coli.
Endotoxin Level	<10 EU/mg
Notes	1. Avoid aeration and bubble formation during dissolution and filtration as they may cause protein denaturation. 2. Insulin solution should not be autoclaved. 3. For your safety and health, please wear a lab coat and disposable gloves during operation. 4. This product is for research use only.
